I am new to rotary, and i am trying to get as close as i can to 300 out of an s5 motor. Just bought my shell and looking for a motor right now. Ive heard that a s5 motor with a Knightsport hybrid turbo can get around 265 to the wheels. Any suggestions or advice would help. Thanks!
300hp out of a 89 Rx7 13b Turbo (S5)

If you plan to turbocharge your NA, its a good idea to swap in the transmission and rear end from a turbo2 at the very least.
The answer is yes, though. There are a lot of guys in FCs making well over 300hp.
Here's a start. Prepare your wallet. lol

S5 = Series 5 which is any 89-91 RX-7.
Is it a turbocharged motor? I'm asking because it comes with a t2 transmission. Whatever the case, the rear end from a naturally aspirated model (coupe, GXL, etc) won't hold 300whp. You'll need the full T2 drivetrain, including the rear end to do the swap correctly.

Biggest question not asked: Is the car the engine/trans/rear end is going into a S5 (89-91) or S4 (86-88). If S4, you're in for a lot of work as the wiring harnesses are not the same and incompatible. Also, what is your plan for engine control? The stock ECU will not be able to support 250+ whp. At the very least you will need larger injectors, a fuel cut defender (if keeping the stock ECU), and something to modify fuel timing (Rtek is the easiest).
There's not much rotary support here. Check RX7Club for the most history but there's a also lot of technical information and experience on RotaryCarClub and NoPistons.
